Always map the repo dir.
Always map the repo dir.

Currently if the repo dir you specify via the environment is on-core on on-tasks it doesn't get mapped due to the mapping being in the else clause of the special-casing that maps them into the node_modules directories of the other projects.

This fixes that, allowing easier development of on-core and on-tasks.

Fixes #499
